The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. of the Alpine Fault R.M. The Alpine Fault • Running about 600km up the spine of the South Island, the Alpine Fault is the on-land boundary of the Pacific and Australian tectonic plates. Le cisaillement sud armoricain [2] dans la partie sud du Massif armoricain. In the middle the Alpine Fault is a transform boundary and has both dextral (right-lateral) strike-slip movement and uplift on the southeastern side. [9] However, it is now inferred by multiples lines of evidence that the Alpine Fault ruptures creating major earthquakes about every few hundred years. These had previously been determined to have occurred in approximately 1100, 1430, 1620 and 1717 CE, at intervals between 100 and 350 years. You can pick out the line of the Alpine Fault on this satellite image of the South Island. ... Each type is the outcome of different forces pushing or pulling on the crust, causing rocks to slide up, down or past each other. [5] The Alpine Fault is not a single structure but often splits into pure strike-slip and dip-slip components. When tectonic forces overcome this locking, the fault slips, jumping up to a distance of 8 metres at a time. She is one of the leaders of the Deep Fault Drilling Project of New Zealand's Alpine Fault, and was a research scientist on the Japan Trench Fast Drilling Project. I'll See You Soon 05:36 Show lyrics (loading lyrics...) 4. The name "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it. Project Number: 430W1444 DISCLAIMER This report has been prepared by the Institute of Geological and Nuclear Sciences Limited (GNS Science) exclusively for and under contract to West Coast Regional Council. The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. Researchers are studying the Alpine Fault to investigate past earthquakes, mountain formation and the structure of the Earth’s crust. Guided educational tours to the natural exposure of the Alpine fault, at Gaunt Creek, near Whataroa, South Westland. The Australian plate is sliding horizontally towards the north-east, at the same time as the Pacific plate is pushing up, forming the Southern Alps. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that broke away from the Gondwanan supercontinent about 83 million years ago. The average slip rates in the fault's central region are about 38mm a year, very fast by global standards. It had a maximum perceived intensity of VII (severe) on the Mercalli intensity scale. Unless otherwise agreed in writing by GNS Science, GNS Science accepts … Alpine d'occasion - s’il est impossible de dénicher une A 110 pour moins de 50 000 €, on peut s’offrir une A 310 ou une A 610 à partir de 20 000 €. Hours Today: 9:30 AM - 6:00 PM . [4], The Indo-Australian Plate is subducting towards the east south of the South Island and the Pacific Plate is subducting towards the West to the north. The epicentre is estimated to have been within a zone extending 50 km northeast from Whanganui towards Taihape. The Alpine Fault then runs the length of the South Island just west of the Southern Alps to near Lewis Pass in the central northern section of the island. [23] Wellman also proposed in 1964 that the Alpine Fault was a Cenozoic structure, which was in conflict with the older Mesozoic age accepted at the time. The results suggest that ductile localization due to overlying faults may account for a large proportion of the strain observed in exhumed mylonite zones. [Chapter Break] After their ground­breaking paper on the Alpine Fault, Willett was posted to Invercargill and Wellman to another war­time project at d’Urville Island. Here the relative motion between the two plates averages 37–40 mm a year. The 1855 Wairarapa earthquake occurred on 23 January at about 9 p.m., affecting much of the Cook Strait area of New Zealand, including Marlborough in the South Island and Wellington and Wairarapa in the North Island. [27] Researchers also planned to install long term equipment for measuring pressure, temperature and seismic activity near the fault zone. In this paper, we investigate the timing and mineralization depths of AFZ clay mineralization using eight fault gouge … using ground penetrating radar to observe hidden evidence of uplift and horizontal movement.
